Can't add repository

Why can’t I add
http://download.opensuse.org/repositories/KDE:/Extra/openSUSE_Leap_15.0/x86_64/
as a software repository? It says “Unable to create repository”

Thanks,
Jim

http://download.opensuse.org/repositories/KDE:/Extra/openSUSE_Leap_15.0/
This is the URL.

Try removing that final “x86_64/” from the URL that you are using.

Explanation: Setting up the repo requires accessing the meta-data. And your URL is too deep, so that no meta-data is found.
